We’ve all seen stars embark on ‘farewell tours’ which turn out to be anything but when they realise they enjoy performing too much.

But, for now at least, Vincent Simone and Flavia Cacace are adamant that The Last Tango - heading for the Liverpool Empire next month - will be just that.

“We’ve been touring for about seven years,” explains Flavia. “We sort of feel it’s right to do the trilogy that we always had in our mind.

“That will take us to about eight years of touring by the time that’s done - hoping that our legs carry on!

“Then it will be nice to put our energy into something different. Dance-related, but not be on the road so much.”

The ‘trilogy’ she’s talking about started with the dancers’ hit show Midnight Tango, set in a late night bar in downtown Buenos Aires and featuring some of the world’s top tango dancers.

That was followed by Dance ‘Til Dawn, which they described as a ‘comedy thriller’ which involved two narrators to explain the story running through its various dances.

Now there’s The Last Tango, their Return of the Jedi perhaps (although without the ewoks of course).

“The show is a little bit more intimate, a little bit more personal,” says Flavia, “a little bit more Argentine Tango feel to it, but it has a lot of different styles as well.

“And because it’s more personal to us, we’re going to recreate some of our favourite numbers from the past, our favourite songs that we’ve performed to.

“Then there’s going to be a whole new array of new songs, new music, new choreography - and maybe even push the boundaries, because we’re a little bit mad, trying out some styles of dancing we haven’t done before.”

It’s hard to imagine there’s a style of dance the diminutive duo haven’t tackled in their careers.

Flavia started dance classes in Guildford at the age of five, working her way up through a series of exams until it was suggested that she go into competitive dance, aged 14.

Vincent, meanwhile, comes from a family of dancers - both his parents are ballroom and Latin teachers, and he himself taught dancing from the tender age of 12 in his native Italy.

He moved to Guildford at 17, where he was introduced to Flavia, and they’ve been dance partners now for two decades.

I wonder out loud if they ever argue about what they’re going to do?

“All the time,” laughs Vincent. “Actually, we’re kind of boring because we never argue.”

Flavia adds: “We pick on each other and make fun of each other.”

“Yes,” joins in Vincent. “We make like a naughty schoolboy.

“But apart from that, we enjoy what we do so much we’re kind of lucky.

“We know loads of other couples and they can’t stand each other - I don’t know how they can dance together even!

“We get on. We’re best of friends and we do what we love the most.”

It’s a long time since the pair were a romantic as well as professional partnership.

These days Flavia is married to former Strictly Come Dancing contestant, actor Jimi Mistry.

And Vincent is dad to two young boys, his ‘sausages’ as he calls them. Last summer he married long-term partner Susan Duddy.

“I don’t know how all the women will take this news,” he jokes. “I think we should open a chatline or something for these people.

“A helpline sorry!”

If The Last Tango really is a full stop on their live touring, what IS next for the pair?

“At the moment all our energy is being put into The Last Tango,” says Flavia, “and making it the most amazing show we possibly can.

“But as dancers we’ve got so many amazing opportunities of things we can do. I think it will be fantastic to put our energy and excitement into something else.
